Etymology: Eviota: No etymology given, suggested by Christopher Scharpt: from Latin 'eu' for 'true' and 'iota' for anything very small, in combination 'truly very small' referring to it as being the smallest vertebrate at the time it has benn described by Jenkins (thus, making the suggestion by Scharpt plausible..

Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 29 m (Ref. 86942). Tropical; 19°N - 20°S
Western Central Pacific: Fiji where there are confirmed records from numerous localities. Other records from throughout the western Pacific Ocean may represent a species complex.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 2.1 cm SL male/unsexed; (Ref. 113727)
soft rays: 7 - 8. This species is distinguished by the following characters: cephalic sensory-canal pore system lacking only the IT pore (pattern 2); branched pectoral-fin rays; dorsal/anal-fin formula 9/8; the fifth pelvic-fin ray is 10-20% of fourth ray; absence of postocular spot; without dark spot on preural centrum area nor prominent dark spots on pectoral-fin base; caudal fin with strong scattered well-spaced dark spots (Ref. 107299).
Inhabits sheltered reefs in 1-20 m (Ref 90102). Occupies a limited range of substrates: dead reef, dead reef with silty sand, silt, and also fine sand (Ref. 116739).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00277 - 0.01371), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
